Nowadays, grapes are growing successfully and well adapted to Poland weather conditions.
-
Chemical composition of interspecific hybrids of V. vinifera species have been developed.
-
Polyphenolic compounds were identified by LC-PDA-QTOF/MS and quantified by UPLC-PDA-FL.

The
study evaluated fruit quality parameters and chemical properties
(soluble solids, pH, total acidity and total sugars content, phenolic
compounds and antioxidant activity (ABTS, FRAP and ORAC methods)) of 30
grape cultivars of white, red and pink grape, as 28 interspecific
hybrids and 2 Vitis vinifera L. popularly grown in Poland. Some
of them were analyzed for the first time. A total of 49 polyphenolic
compounds were identified by LC-PDA-QTOF/MS and quantified by
UPLC-PDA-FL, as 26 anthocyanins, 9 flavonols and flavons, 7 phenolic
acids, 6 flavan-3-ols, and 1 stilbene. The content of total polyphenols
ranged from 1037.0 (Cascade cv.) to 5759.1 mg/100 g dm (Roesler cv.).
However, the content of stilbene represented by trans
resveratrol-3-glucoside was only 18.5–70.5 mg/100 g dm. Red grape
cultivars like Roesler, Rothay and Swenson Red were characterized by the
highest content of bioactive compounds and antioxidant activity
(significantly more than 24, 12 and 53 mmol TE/100 g dm, by ABTS, FRAP
and ORAC, respectively). Average total acidity and soluble solids for
white (0.95 g of tartaric acid in 100 g fm and 17.1°Bx, respectively)
and for red and pink (0.93 g of tartaric acid in 100 g fm and 17.4°Bx,
respectively) cultivars were not significantly different (p > 0.05).
